Passable very early film about the planets in our solar system. Of course, no real lifelike photography existed of this at the time, so we're stuck with illustrations. The first 1/4 of the film deals with the atmosphere and what not on earth, and then the film goes exploring, by having a plane go to the moon. So they get some things right and wrong, but hey, it's the 20s, so they're allowed to make mistakes.
